Abstract
Description
- In the resource recovery industry boreholes are formed in a formation for the purpose of stimulating and or producing formation fluids. A tubular may be positioned in the wellbore to guide fluids to a surface of the formation. The tubular may include one or more openings that permit formation fluids to enter and flow toward the surface. In many cases, a screen will be positioned over the one or more openings in order to prevent or at least limit debris from passing into the tubular with the formation fluid.
- Often times, a valve is arranged in the tubular at the one or more openings. The valve may control access for the formation fluid entering the tubular. The valve, tubular, and screen are formed off-site, transported to a well site, and run into the borehole. Constructing a valve and screen assembly is a time consuming endeavor that requires forming threads, installing the valve in a tubular, making up multiple connections, and constructing a screen about the tubular. Given the cost and complexity of forming a screen and valve assembly, the industry would welcome simpler, more cost effective and easily repairable systems.

The drop ball or other device may be employed to shiftvalve element 144 to open and close a flow path by aligning plurality ofopenings 162 with at least oneopening 124 thereby allowing formation fluids to pass intotubular string 30 and flow towardsurface system 16. -
Valve member 56 is arranged infirst conduit section 74 andsecond conduit section 98.Valve member 56 may be held in place by a compressive force that is generated by engagingfirst connector portion 80 andsecond connector portion 104 when joiningfirst screen portion 52 andsecond screen portion 54. It should be understood thatvalve member 54 is devoid of any connectors. That is, neitherfirst end segment 114 norsecond end segment 116 includes a connector that interfaces withfirst screen portion 52 andsecond screen portion 54. It should also be understood that the compressive force is generated during installation. Given the presence ofcasing tubular 40, no compressive, tensile, or torsional forces are seen byvalve member 56 after installation. With this arrangement, screen andvalve system 50 may be constructed on site. Further, screen andvalve system 50 may be readily repaired in the field. Thus, the present invention reduces manufacturing costs, delivery costs, and maintenance costs of the screen assembly. - Reference will now follow to
